DETAILED DESCRIPTION

To make the objectives, technical solutions, and advantages of embodiments of the present application clearer, the following clearly and completely describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are part rather than all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. Hot plugging, that is, hot swap, refers to that a module and an expansion card are plugged in or unplugged from a system without affecting normal work of the system in a case of not shutting down a power supply, which can improve reliability, rapid maintainability, redundancy, capability to recover disasters in time, and the like of the system. A bus module is generally connected to an interior of a case by bolts. An operator needs to open an upper cover of the case, and then installs the bus module in the case. This installation manner is complex, and the module cannot be assembled and disassembled in a case of not shutting down a system power supply. To facilitate assembly, disassembly, and maintenance of the bus module, the bus module needs to be configured to be hot pluggable. To facilitate plug-in maintenance of the bus module, in a related art, a first connector is also arranged at a slot of the case, and a second connector is arranged on the bus module. The first connector can be plugged with the second connector. However, in such a bus module, a hole position in a blocking piece of the bus module is in an idle state, the blocking piece on a bus network interface card is L-shaped, so that the blocking piece needs to occupy a relatively large space in a housing, thereby increasing an overall size of the bus module. To save space, the blocking piece needs to be removed, and a new blocking piece needs to be customized. However, an original manufacturer of the bus network interface card is not maintained any longer due to the removal of the blocking piece, which brings inconvenience to a customer. To customize the new blocking piece, a system factory needs to newly develop spare parts for fixing screws of the blocking piece, which will increase the cost of the bus module. In addition, both the first connector and the second connector are high-density connectors, which results in great plugging and unplugging resistance of the first connector and the second connector. To facilitate force application of an operator, a handle is generally arranged on a housing 1 of the bus module. When the bus module is plugged into a slot 701 of a case 7 , the handle is located at a notch of the slot 701 , and the operator can apply a force to the bus module through the handle. However, the operator needs to apply a relatively great force to complete plugging and unplugging operations of the bus module through such a handle. In addition, the handle is located at the notch, so that a relatively large space in the slot 701 needs to be occupied. Embodiments of the present application are described with reference to FIG. 1 to FIG. 18 . According to an embodiment of the present application, in a first aspect, a bus module is provided. The bus module is configured to be plugged into a slot 701 of a case 7 , and a first connector 702 is arranged in the slot 701 . The bus module includes a housing 1 , a bus network interface card 2 , a second connector 3 , and a lever structure 4 . The housing 1 has a first end and a second end. The second connector 3 is connected to the first end of the housing 1 , and is configured to be plugged with the first connector 702 . The bus network interface card 2 is arranged in the housing 1 , and the bus network interface card 2 includes a network interface card body 201 and a blocking piece 202 . The blocking piece 202 is connected to one end of the network interface card body 201 away from the second connector 3 . A first bending portion 2021 is formed at one end of the blocking piece 202 . The first bending portion 2021 extends in a direction away from the network interface card body 201 . A first shielding portion arranged around the first bending portion 2021 is formed at a position corresponding to the first bending portion 2021 of the housing 1 . The lever structure 4 includes a hinge end, an operating end, and a second bending portion 4014 . The hinge end is hinged to one side away from the first bending portion 2021 of the second end. The second bending portion 4014 is connected to the operating end. The second bending portion 4014 is configured to be in contact with the first shielding portion and is detachably connected to the first shielding portion, and the lever structure 4 is configured to assist in plugging or unplugging of the second connector 3 and the first connector 702 . According to the bus module of this embodiment, a lever structure 4 is arranged at the second end of the housing 1 . An operator can separate the operating end of the lever structure 4 from the second end of the housing 1 first, then hold the operating end of the lever structure 4 , and applies a force through the operating end to assist in plugging or unplugging the second connector 3 and the first connector 702 , so that a plugging and unplugging force required for assembling and disassembling the bus module can be reduced, assembling and disassembling processes are laborious, and labor intensity of the operator is improved. In addition, the bus module in this embodiment remains the original blocking piece 202 of the bus network interface card 2 , and the housing 1 is configured to include the first shielding portion arranged around the first bending portion 2021 . The second bending portion 4014 of the lever structure 4 is detachably connected to the first shielding portion. Through such an arrangement, the first shielding portion is configured to be connected to the lever structure 4 , and one side of the bus network interface card 2 away from the second connector 3 is configured to accommodate the lever structure 4 , so that space of this part of the first bending portion 2021 is fully used, a structure of the bus module is more compact, and reducing of an overall size is facilitated. The bus module of this embodiment cannot occupy too much space while remaining the blocking piece 202 of the bus network interface card 2 , so that the costs are low, and the structure is compact. Therefore, the bus module of this embodiment can overcome defects that a relatively high plugging and unplugging force is required for disassembling and assembling the bus module, the disassembling and assembling processes are laborious, and labor intensity of the operator is improved, and cannot occupy too much space while remaining the blocking piece 202 of the bus network interface card 2 , so that the costs are low, and the structure is compact. Preferably, both the first connector 702 and the second connector 3 are high-density connectors. In one or more embodiments, as shown in FIG. 2 , a first abutting protrusion 4011 is connected at the hinge end. The first abutting protrusion 4011 is in contact with the notch of the slot 701 . When the operator applies a force to the operating end of the lever structure 4 to force the operating end to rotate in a direction away from the housing 1 , the hinge end of the lever structure 4 can rotate reversely, so that the first abutting protrusion 4011 applies a pressure to the notch of the slot 701 to enable the bus module to be falling off from the slot 701 under a counter-acting force at the notch. As a variable implementation, a protruding contact portion is formed on a side wall of the slot 701 , and the first abutting protrusion 4011 is in contact with the contact portion. In one or more embodiments, as shown in FIG. 3 and FIG. 4 , the hinge end includes a second abutting protrusion 4012 , and a contact slot 703 is formed in a slot wall of the slot 701 . The second abutting protrusion 4012 is in contact with a side wall of one side of the contact slot 703 away from the second connector 3 when the second bending portion 4014 is connected to the first shielding portion. The second abutting protrusion 4012 is configured to be separated from the contact slot 703 when the lever structure 4 rotates in a direction away from the housing 1 . Through such an arrangement, when the bus module needs to be plugged into the slot 701 , the operator can plug the bus module into the slot 701 first, and then the operating end is driven to rotate in a direction close to the housing 1 , so that cooperation between the second abutting protrusion 4012 and the contact slot 703 assists in a connection between the second connector 3 and the first connector 702 . The second abutting protrusion 4012 can be constrained within the contact slot 703 after the second bending portion 4014 is connected to the first shielding portion, so as to prevent the bus module from sliding in a plugging direction of the bus module and the slot 701 , thereby preventing the bus module from falling off from the slot 701 under an external acting force or due to an error operation. When the bus module needs to be unplugged from the slot 701 , the operator can release the connection between the second bending portion 4014 and the first shielding portion, so that the operating end rotates in a direction away from the housing 1 , and the second abutting protrusion 4012 can be separated from the contact slot 703 to allow the bus module to be unplugged from the slot 701 . In one or more embodiments, a connecting port is formed in one side of the second end hinged to the lever structure 4 . The hinge end penetrates through the connecting port and is hinged to an interior of the housing 1 . The second abutting protrusion 4012 penetrates through the connecting port and is plugged into the contact slot 703 when the second bending portion 4014 is connected to the first shielding portion. Through such an arrangement, a hinge point between the lever structure 4 and the housing 1 can be located in the housing 1 , which helps to enhance attractiveness of the bus module, and prevent a pollutant from being in contact with a hinge shaft to lead to unsmooth rotation of a lever. The second abutting protrusion 4012 can be located in the housing 1 when a user plugs the bus module into the slot 701 , so that a gap does not need to be formed between the bus module and the slot 701 to accommodate the second abutting protrusion 4012 , and a structure of the case is more compact. In one or more embodiments, as shown in FIG. 5 , the connecting port includes a first connecting port 1013 and a second connecting port 1014 . The first connecting port 1013 and the second connecting port 1014 are respectively formed in two adjacent side walls of the second end. A connecting portion 1015 is formed between the first connecting port 1013 and the second connecting port 1014 . An avoidance opening 4013 is formed between the first abutting protrusion 4011 and the second abutting protrusion 4012 , and the connecting portion 1015 penetrates through the avoidance opening 4013 . The avoidance opening 4013 can prevent the lever structure 4 from interfering with the connecting portion 1015 of the housing 1 during rotating. In one or more embodiments, as shown in FIG. 4 to FIG. 7 , the lever structure 4 includes a lever main body 401 , a locking structure 402 , and an elastic piece 403 . The lever main body 401 has a hinge end, an operating end, and a second bending portion. The locking structure 402 is movably connected to the second bending portion 4014 . The locking structure 402 has a locking position locked and connected to the second end and an unlocking position separated from the second end of the housing 1 . The elastic piece 403 is connected between the locking structure 402 and the second bending portion 4014 . The locking structure 402 can be constrained at the locking position under support of the elastic piece 403 when the bus module is plugged into the slot 701 , and the second abutting protrusion is constrained within a contact slot. An operator can apply a pressure to the locking structure 402 and compress the elastic piece 403 when the bus module needs to be unplugged, so that the locking structure 402 is switched to the unlocking position, then the operating end rotates in a direction away from the housing 1 , and the lever structure 4 assists in unplugging of the bus module. Optionally, the lever main body 401 is a rod-like structure. Preferably, in this embodiment, the lever main body 401 is of a wrench structure hinged to the housing 1 . As a variable implementation, optionally, the lever structure 4 includes a locking knob. The locking knob is rotatably connected to the operating end of the lever structure 4 . A handle portion is arranged at one end, and a limiting strip is arranged the other end. A strip-shaped hole matching the limiting strip is formed in the housing 1 . As another variable implementation, an elastic buckle is arranged on the operating end of the lever structure 4 . A clamping slot that can be clamped with the elastic buckle is correspondingly formed in the housing 1 . In one or more embodiments, a sprouting structure 1018 is protruded from the first shielding portion. A locking gap configured to be locked and connected to the sprouting structure 1018 is formed in the locking structure 402 . Through such an arrangement, the sprouting structure 1018 of the first shielding portion can serve as a connecting structure to detachably connected to the locking structure 402 of the lever structure 4 , and a connecting structure does not need to be added to the first shielding portion, so that a quantity of components required by the bus module can be reduced, and the structure of the bus module is more concise. In one or more embodiments, the locking structure 402 includes a locking sleeve 4021 and a plug-in port 4022 . The locking sleeve 4021 is provided with a locking gap. The plug-in port 4022 is formed in the locking sleeve 4021 .

Through such an arrangement, a connecting direction between the locking sleeve 4021 and the second bending portion 4014 can be perpendicular to a moving direction of the elastic structure, which can prevent the locking structure 402 from releasing a connection with the second bending portion 4014 under support of the elastic piece 403 . Preferably, a locking plate is arranged at a top of the locking sleeve 4021 . The locking gap is formed in the locking plate. The locking plate forms a guide inclined surface at the first edge. The guide inclined surface is inclined downward in a plugging direction of the locking sleeve 4021 and the second bending portion 4014 . When the bus module needs to be locked into the slot 701 of the case 7 , the operator can rotate the lever structure 4 to a direction close to the housing 1 , so that the guide inclined surface is in contact with the sprouting structure 1018 . The guide inclined surface can guide the locking sleeve 4021 to move downward, so that the sprouting structure 1018 is allowed to enter the locking gap, and the sprouting structure 1018 and the locking sleeve 4021 are interlocked. The locking gap is preferably, but not limited to, a semicircular gap, a square gap, a triangular gap, and the like, and is preferably a semicircular gap that accommodate a periphery of the sprouting structure 1018 in a matched manner.

The elastic snap hooks 4023 are configured to extend into the chute 4015 and slide along the chute 4015 . Through such an arrangement, the elastic snap hook 4023 can slide along the chute 4015 to guide and can hook a side wall of the chute 4015 , so as to prevent the locking sleeve 4021 from falling off from the second bending portion 4014 . Preferably, the elastic snap hook 4023 includes a clamping surface and a guide inclined surface that are sequentially connected in a direction in which the elastic snap hook 4023 is clamped into the chute 4015 . The clamping surface is parallel to the side wall of the chute 4015 , and can be in contact with the side wall of the chute 4015 after the elastic snap hook 4023 is clamped into the chute 4015 . The guide inclined surface is inclined toward a direction close to the side wall of the plug-in port 4022 in the direction in which the elastic snap hook 4023 is clamped into the chute 4015 . Through such an arrangement, the guide inclined surface can guide side walls of two sides of the plug-in port 4022 to be separated from each other when in contact with the second bending portion 4014 , so that the second bending portion 4014 is allowed to enter the locking sleeve 4021 . Preferably, there are a plurality of elastic snap hooks 4023 . In a deformation direction of the elastic piece 403 , the plurality of elastic snap hooks 4023 are arranged on groove walls of the two sides of the plug-in port 4022 , so that a contact surface between the locking sleeve 4021 and the second bending portion 4014 is stressed more uniformly, and the locking sleeve 4021 slides more smoothly. In one or more embodiments, two ends of the elastic snap hook 4023 are respectively configured to be in contact with corresponding chute walls of the chute 4015 . Through such an arrangement, an upper wall of the elastic snap hook 4023 can be in contact with the chute wall of the chute 4015 when the locking sleeve 4021 moves upward with jacking of the elastic piece 403 , and the locking sleeve 4021 is prevented from falling off from an upper part of the second bending portion 4014 due to the jacking of the elastic snap hook 4023 . In one or more embodiments, the elastic piece 403 is a spring, and the locking structure 402 further includes an accommodating blind hole 4024 .

In one or more embodiments, an edge of the lever main body 401 opposite to the network interface card body 201 is defined as a second edge when the second bending portion is connected to the first shielding portion. A first limiting protrusion 4018 is formed on the second edge. A first limiting groove 1017 configured to accommodate the first limiting protrusion 4018 is formed in the housing 1 .
